If the time for wiping over the socks ends or he takes off his shoes, is his wudoo’ invalidated?

Question

What shall I do when I remember during my prayer that the period of wiping on shoes has run out? Should I break my prayer?
If I wore socks under my shoes after ablution (wudu’), then took my shoes off while socks still on, does this invalidate my ablution?.

If the time for wiping
over the khufoof has ended, and you have wudoo’, then your wudoo’ does not
become invalidated, according to the correct view, which was favoured by a
number of scholars, including Ibn Hazm and Shaykh al-Islam Ibn Taymiyah (may
Allaah have mercy on them), because there is no evidence that it becomes
invalidated. Wudoo’ is only invalidated by the well known causes such as
passing wind. See question no.

Based on this, if the
period (for wiping over the socks) ends whilst you are praying, then you
should carry on with your prayer, and pray as much as you want so long as
you do not break your wudoo’.

Secondly:

If a person takes off the
khufoof or socks after wiping over them, his wudoo’ does not become
invalidated according to the correct scholarly opinion. That is because when
a man wipes over his khufoof, he has completed his purification according to
the shar’i evidence, and when he takes them off, this purification remains
in effect, based on shar’i evidence, and it cannot be rendered invalid
except with shar’i evidence. There is no evidence that taking off khufoof or
socks that have been wiped over invalidates wudoo’. Based on this, his
wudoo’ remains in effect. This is the view favoured by Shaykh al-Islam Ibn
Taymiyah and a number of other scholars. See: Majmoo’ Fataawa Shaykh
al-Islam Ibn Taymiyah (21/179, 215) and Majmoo’ Fataawa wa Rasaa’il
al-Shaykh Ibn ‘Uthaymeen (11/179).

But taking off the khufoof
brings the period for wiping over them to an end, i.e., he cannot put them
on again and wipe over them, until after he does a complete wudoo’ in which
he washes his feet.
